如何讓兩個Div相對於其他的固定？

Question

我有一個div下面是一個按鈕，因爲我的屏幕大小改變了Div的變化高度，因爲按鈕改變了它的位置，有時它隱藏在Div後面，因爲我提供了z-index。即使屏幕大小發生變化，我怎樣才能確定相對於Div的固定按鈕的位置？

這裏是我的HTML代碼： -

<div class="row" id="event"> 
      <div class="col-lg-1 col-md-1 col-xs-1"></div> 
      <div class="col-lg-10 col-md-10 col-xs-10 "> 
      <section *ngFor="let event of events; let i = index" [style.backgroundColor] = "colorsArray[i]" class="eventSectionCSS"> 
       <legend class="legendCSS"> {{event.title}}</legend> 
<br> 

       <div class="row" style="margin-left: 15px;" > 
       <div class="col-lg-6 col-md-6 col-xs-6" style="display: inherit;" > 

        <div class="row" > 
        <div class="col-md-6 col-lg-6 col-sm-6 col-xs-6"> 
         <h2 class="presenterNameCSS" >{{ event.SMEPresentedByFirstName | uppercase}} </h2> 
        </div> 

        <div class="col-md-6 col-lg-6 col-sm-6 col-xs-6" style="margin-left: -10px;" > 
         <h2 class="presenterNameCSS" > {{ event.SMEPresentedByLastName | uppercase}} </h2> 
        </div> 

        </div> 

       </div> 
      <div class="col-lg-3 col-md-3 col-sm-3 col-xs-3" ></div> 
       <div class="col-lg-3 col-md-3 col-sm-3 col-xs-3" id="image__event_both" > 
        <div class="col-lg-6 col-md-6 col-xs-6"> 
             <div class="flip-container" ontouchstart="this.classList.toggle('hover');">

您可以通過使用相對位置實現這一目標。固定的位置與屏幕相關。

您更新的小提琴沒有顯示實際情況。我看不到固定在按鈕上的位置。
